From the statistical point of view, if the target phenotype is considered as independent variable and allelic variation in many genome loci as explanatory variables, we need to pick up the variables with significant contribution to the phenotype from tens of thousands of variables. This is so-called variable selection from oversaturated models. There has been many methods to deal with this issue.

從統(tǒng)計學的角度來看日本黄页网站免费大全37699，如果把目標性狀表現(xiàn)型看作依變量，基因組上很多座位的序列變異看作自變量，則需要在成千上萬個自變數(shù)中篩選出一些對表型有顯著效應的自變數(shù)日本免费A片人人片人人C人人，因此，該問題可以看作是一個超飽和模型變數(shù)選擇的問題午夜免费播放成人无码视频在线看。

Firstly, the research tests the stationary of each variable by adopting the Unit Root Test and all variables shows I(1) sequence. Secondly, it tests the stability of each variable by adopting Perron (1989) structure transformation Unit Root Test. The test result is same as the ADF test, which does not consider the structure transformation.

The results showed that food ingestion and frequency of the polecat in constant food patches were higher than that in the variable food patches and time of the polecat was the same between two patches during the training period. Only the frequency of the polecat in constant food patches was higher than that in variable food patches when the polecat was starved for 1 day. Its foraging pattern between the two patches was the same as that during the training period when the polecat was starved for 2 days. Meanwhile, the food ingest ion amount in the two patches was not affected by starvation, but the time and frequency of the polecat using the two patches significantly decreased when starvation increased.
